I would have thought that HT was "time-sharing" (remember that? :) built
into
a PC's CPU. So it seemed very wrong for my machine to be splitting it's

time

between idle and sah.

HT is actually based on the premise that at any given time, the bulk of a
processor's capacity isn't in use.  Intel added a second set of microcode
control registers so that two different threads can be processing at the
same time, with only minimal interference with each other.
